When the proxy is set, any application including the browser 10a requests the operating system 100a to transmit the request according to the communication protocol through the communication API provided by the operating system 100a. The operating system 100a checks the proxy setting state, and if the proxy-set IP address is an internal IP address, an application assigned with the internal IP address, in this case, requesting transmission of a request by a communication protocol with the local server 113. The internal sockets 21a and 21b for communication between the browsers 10a are respectively generated between the browsers 10a and then the requests and responses according to the communication protocol are transmitted to each other through the generated internal sockets 21a and 21b.

In other embodiments according to the present invention, an external IP address is intercepted by a request made by a communication protocol transmitted by an application in the mobile communication terminal 100, for example, an HTTP request, and the request is made by an internal IP address. It may be redirected to the local server 113. Alternatively, a method may be applied in which an application inserts an internal IP address assigned to the local server 113 into a host field of a request by a communication protocol to be transmitted to the outside.

When receiving a request according to a communication protocol from a process or an application external to the data communication manager 110 by any one of the above-described methods, the local server 113 transmits the request according to the received communication protocol to the data transmission / reception unit. And the data transmission / reception unit 112 generates the communication socket for use of the currently connected communication network to the operating system 100a by using the information contained in the request according to the received communication protocol. request. When a communication socket 22 ₁ for data transmission and reception with the outside is generated in response to the request, the data transmission / reception unit 112 requests a request according to the received communication protocol through the communication socket 22 ₁ through the operating system ( Forwards the request to 100a). At this time, the data transmission / reception unit 112 stores in association with the request according to the communication protocol requesting the transmission to the communication socket (22 ₁ ). This is to use the information of the request in order to receive successively without missing data even when the communication network used is switched during data reception. In addition, the data transmission and reception unit 112 also monitors the amount of data received through the corresponding communication socket (22 ₁ ) after the request for transmission according to the communication protocol. This is for the same reason as above, and the operation for this will be described later in detail. If the amount of data to be monitored corresponds to all of the data requested by the transmitted communication protocol, the request according to the communication protocol stored in association with the communication socket 22 ₁ is deleted and the amount of data to be monitored is also reset to zero. Will be set.

On the other hand, the operating system (100a) receives the request according to the transmission protocol transmitted from the data transmission and reception unit 112, configures the IP packets and transmits them to the content server 12 (the transmission is currently Or via the Wi-Fi codec 2b / Wi-Fi modem 2a, depending on the communication network to which it is connected, or accordingly. The response from the server 12, for example the requested content, is transmitted to the data transceiver 112 via the created communication socket 22 ₁ . The received response is transmitted back to the local server 113 by the data transmission / reception unit 112, and the local server 113 generates a request based on an initial communication protocol through internal communication sockets 21b and 21a. To the external application, that is, the browser 10a. The browser 10a causes the contents described in the response to be displayed on the display panel 5, or if the mime-type cannot be processed by itself, for example, if the image content is an appropriate application, eg For example, the media player 10b is called.

On the other hand, the reception control unit 111 selects one mode based on the currently set mode policy 110b and checks the wireless network usage requirements specified for the selected mode from the currently set mode profile 110a. Done. 3A is an example of the mode profile 110a defining usage requirements for at least one mode. Three modes are defined. 3B is an example written for the mode policy 110b according to an embodiment of the present invention, and illustrates that one mode is selected according to the day of the week and the time zone. For example, if the current time point identified from the operating system 100a is “weekday” and the current time is between 10 am and 5 pm (311), the reception controller 111 may perform the illustrated mode policy 110b. The mode B is determined based on the above, and the content profile requirements for use of the wireless communication network defined by the determined mode B are checked from the mode profile 110a. In the example for the detailed description of the present invention, the mode profile (110a), whether or not to limit the use speed and / or limit value for the cellular network (11a) used as a specific wireless communication network, for example, public telephone communication network ( Since "throttling value" is designated as the use requirement, the reception control unit 111 sets the deceleration value 301 specified in the determined mode B to the data transmission / reception unit 112. The value set as the deceleration value of the mode profile 110a may be zero. This is a value to completely stop using the data service for the communication network to be slowed down, for example the cellular network 11a.

In another embodiment according to the present invention, the mode policy 110b may be defined such that one mode is designated according to the location of the terminal. 3C is one example of the mode policy 110b thus created. In the example of FIG. 3C, a service area is one service area (hereinafter also referred to as a "cell") in the cellular network 11a or an arbitrary access point of the Wi-Fi network 11b. It may be a service zone by an access point (AP). It may also be any section belonging to the service area. In the following description, the term “service area” is used interchangeably. Thus, the service area of FIG. 3C can be specified in various ways. For example, in the service area of the cellular network 11a, a cell identifier, in the case of a service zone of an access point, an identifier of an access point (for example, an MAC address of an access point), and a center in an arbitrary specific area. It can be specified as longitude and latitude coordinates and radius information or as a femto cell identifier. Accordingly, the reception control unit 111 confirms which service area described in the place reference mode policy 110b in which the information on the current location to be checked corresponds to the location-based mode policy 110b in which an example is shown in FIG. 3C, and corresponds to the identified area. To determine the mode to use. For example, if the information on the currently confirmed location corresponds to the “service area G” of FIG. 3C, the reception controller 111 determines the current mode as mode B (321), and the determined mode B defines the current mode. Information on the requirements for using the wireless communication network is confirmed from the mode profile 110a. Of course, if this move to another service area after the determination, the other mode is determined again accordingly. A method for obtaining information about the current position by the reception controller 111 will be briefly described later.

In one embodiment according to the present invention, for the mode policy 110b, the illustrated day / time zone criteria of FIG. 3B and the place criteria illustrated in FIG. 3C may be created together. In the case of the mode policy 110b in which both standards are defined, the reception controller 111 may select each mode according to both standards and then determine a mode that specifies a more stringent use requirement as a use mode. Alternatively, if the service area for the current location is not identified in the sub-policy based on the place criteria (example of FIG. 3C), the sub-policy based on the day / time zone (FIG. The mode may be determined based on the example of 3b). At this time, it is not necessary to separately define the area in which the deceleration of data service use is not specified in the subordinate policy (example of FIG. 3C) based on the location. That is, in the example of FIG. 3C, mode information for the remaining zones 322 may be removed.

As described above, when the response according to the request by the transmitted communication protocol is received, when the deceleration value according to the use requirement is set by the reception control unit 111, the data transmission / reception unit 112 may The operating system 100a reads data received and filled in the communication socket 22 ₁ created for mutual communication with the operating system 100a without any limitation, and transfers the data to the local server 113. However, as described above, when the deceleration value is set from the reception control unit 111, the generated communication socket 22 ₁ is read when the communication socket using the cellular network 11a to which the deceleration value is to be applied. With the speed as the upper limit of the deceleration value, data accumulated in the communication socket 22 ₁ is read. That is, if the data rate that the data communication manager 110 receives for intermediary for another process or application is above the deceleration value on average, the reception rate is reduced. It is possible to know from which network connection information the created communication socket is used. For example, the network connection information obtained by inquiring the operating system 100a includes a connection type (for example, a 3G mobile telephone communication network, a Wi-Fi wireless LAN network) with a current communication network, and the data transmission and reception. The unit 112 confirms the current communication network from the connection type information obtained according to the inquiry, and records the created communication socket at the time using the socket using the communication network.

In order to reduce the reception speed, the data transmission / reception unit 112 may notify from the operating system 100a that the data has been stored in the communication socket 22 ₁ or at any time, as illustrated in FIG. 4, After reading all the data 401 filled up to the communication socket 22 ₁ up to that time, check the read data amount DS _k and make the deceleration value set to the deceleration value set for the data amount DS _k ( _I ) Calculate time T _idle1 (411). When the idle time T _idle1 is calculated, the data transmission / reception unit 112 does not change the data even when the communication socket 22 ₁ is filled by the operating system 100a until at least the idle time has elapsed. Do not read data. If the deceleration value is 0, the operation of reading data of the corresponding communication socket 22 ₁ is stopped without calculating the above idle time. When the deceleration value is not 0, after the idle time T _idle1 elapses, a read operation on the communication socket 22 ₁ is performed at any time at a possible time point 421. If the wireless communication network to which the deceleration value is applied, for example, a communication socket using the cellular network 11a is further included in addition to the communication socket 22 ₁ , the time when the idle time T _idle1 elapses or thereafter and it performs the read operation for the next communication socket (22 _2). If there is no data accumulated in the corresponding communication socket (22 ₁ or 22 ₂ ) at the time of reading, the next communication socket is checked in order, and if there is any accumulated data, the read operation is performed as shown in FIG. By recalculating the idle time according to the data amount, the data read operation for the corresponding communication socket or the next communication socket is stopped during the corresponding time period. Until it lasts. Of course, when a new deceleration value is set, the idle time is calculated after reading data from the communication socket by applying the deceleration value.

If the data is not filled in the corresponding communication socket 22 ₁ (or the next communication socket in sequence) after the calculated idle time T _idle1 , the data is filled in any other communication socket regardless of the order. In this case, the data read operation is performed. Of course, even after this data read operation, the idle time is calculated for the read data amount as described above to wait for the idle time or more. If no data is filled for any communication socket after the calculated idle time has elapsed, wait until the data is filled for any communication socket or until such notification is received from the operating system 100a. In this case, although the deceleration value is set by the reception control unit 111, the average speed of data received through the cellular network 11a from the external server including the content server 12 is actually set by the deceleration. Can occur when lower than

If the speed of data received from the external server including the content server 12 via the cellular network 11a before the deceleration of the data rate is higher than the set deceleration value, Due to the deceleration of the reading speed, the communication socket 22 ₁ (or other communication sockets using the same communication network) for communication between the data transmitting and receiving unit 112 and the operating system 100a is timed. As time goes by, the data becomes full, and when this state is reached, a communication protocol for point-to-point transmission executed in the operating system 100a, for example, According to the Data Flow Control (TCP) of the Transfer Control Protocol (TCP), data is transmitted to a remote location, that is, through a wireless communication network to which an average transfer rate (or a deceleration value) is applied at the content server 12. The average speed of the total data from all the servers transmitting to the scene manager 110 is decelerated, and the speed converges to the deceleration value. Therefore, the traffic load applied to the cellular network 11a occupied by the wireless communication resource by the response data received by the wireless communication terminal 100 is reduced to an amount corresponding to the deceleration value.

In another embodiment according to the present invention, the reception control unit 111 is configured to mediate response data transmitted from the data transmission / reception unit 112 to the local server 113, whereby the reception control unit 111 is currently designated. According to the deceleration value, the data reception speed may be reduced. 5 is a view for explaining the present embodiment, the data transmitting and receiving unit 112 receives the response data received through the communication socket 2 _{1 1} , the receiving buffer that the drawing is made by the receiving control unit 111 (111a) (which can be implemented through a shared memory or a file) is stored within the range of free space (S51). The data stored in the reception buffer 111a is withdrawn by the reception control unit 111 (S52) and transferred to the local server 113, and the reception control unit 111 at this time is the amount of data transferred and the current mode. Based on the deceleration value specified in FIG. 4, as illustrated in FIG. 4, the idle time T _idle1 is determined. Until the idle time has elapsed, even if some data is filled in the reception buffer 111a, the data is not read and transferred to the local server 113. In this state, when the receiving buffer 111a is completely filled within the idle time, the data transmitting / receiving unit 112 does not read data from the communication socket 22 ₁ , whereby as described above, By the point-to-point data flow control of the operating system 100a, the speed of data using the cellular network 11a converges to the deceleration value or less. That is, the use of the cellular network 11a of the wireless communication terminal 100 is limited to below the deceleration value.

Instead of the reception control unit 111 withdrawing data from the reception buffer 111a and transferring the data to the local server 113, the reception control unit 111 notifies the local server 113 of the deceleration value specified in the current mode. When the local server 113 reads data from the space for receiving data from the data transmission / reception unit 112 (for example, the reception buffer 111a of FIG. 5), the read data amount and The same result as described above can be obtained by determining the idle time as described above according to the notified deceleration value and not reading data from the space at least within the determined idle time.

In another embodiment according to the present invention, unlike the above-described embodiments in which the received data is accumulated, the data is received within the deceleration range set in the current mode by adjusting the size or time interval of the requested data. In the present embodiment, if the current deceleration value is set, the data transmission / reception unit 112 receives a response to the request by the communication protocol received from the local server 113 and relayed to the operating system 100a. This is first transmitted to the reception control unit 111. The reception control unit 111 confirms from the information described in the response whether the response is a data object of considerable size, for example, several MBytes or more, for example, a content file of video or audio, and the response containing such data object is Otherwise, the location information where the received response data is stored, for example, the name of a temporary file, is transmitted to the local server 113 as it is.

If the received response is for a data entity of considerable size, the reception control section 111 requests a request by a communication protocol to stop transmission of the data entity, to which the response is sent, for example, the content server. 12), and the data of the entity is divided into sections of an appropriate size S _{SEG_k} , as illustrated in FIG. 6, using the size information. In order to know the total size of the data entity 60, a request by additional communication protocol may be transmitted and received. Instead of dividing each section at a time when the size of the data entity is known, the section may be determined by determining the size of the section at the time of actually requesting the section. At this time, the size of the division section may be equal. When the section is determined, the reception control unit 111 creates a request based on a communication protocol requesting the first section 60 ₁ , for example, an HTTP request 610 ₁ , and transmits it to the data transmission / reception unit 112. The data transmission / reception unit 112 transmits the requested transmission request to the content server 12 through the operating system 100a. Accordingly, the requested data of the corresponding section is transmitted to the reception control unit 111 through the data transmission / reception unit 112, and the reception control unit 111 transfers the transferred data to the local server 113. do. At this time, data transfer between the data transmission / reception unit 112 and the reception control unit 111 and between the reception control unit 111 and the local server 113 is, in fact, location information that can access the data. (Such as a memory address or the name of a temporary file).

Meanwhile, as illustrated in FIG. 7A, the reception control unit 111 transmits a request according to a communication protocol for requesting a corresponding section (t701), and then the data size (S _{SEG_1} ) of the requested section 71. The idle time T _idle2 is calculated from the designated deceleration value in the current mode (701). When the stop time (T _idle2) is calculated, the reception controller 111 the calculated idle time (T _idle2) at the time (t702) is received segment 71 with the request from the data transmitting and receiving unit 111 The reception control unit 111 does not proceed with the request for the next section (60 _{2 in} FIG. 6) until the timer of size is driven and the timer is timed out. When the timeout occurs (t703), the reception control unit 111 checks whether the data of the previously requested section 71 is still being received even at that time point (S701). Wait until (S703). When the reception is completed at the time-out time t703, a request 610 _{2 based} on a communication protocol requesting the next section is created and transmitted to the data transmission / reception unit 112 (S702). If there is another data object, for example, a content file, to be divided and received in intervals (if there is a response to a request by another communication protocol received from the data transmission / reception unit 112), the reception control unit 111 determines the time. When it is out (t703), the transmission request is made while making a request according to a communication protocol for a division section that is currently requested in the order of the other data entity and transmitting it to the data transmission / reception unit 112. As described above, the idle time is calculated for the requested section, and the idle time is waited. This operation is performed recursively for each data object that is requested individually.

In the example of FIG. 7A, when timed out (t703), if the data of the previously requested interval is still being received, this may be the case when the data rate required for play of the data entity is lower than the currently set deceleration value, or the wireless communication network. It may be the case that the current service speed provided through or the transmission speed of the server transmitting the data object is lower than the set deceleration value. In any case, since the currently requested data entity is a load on the wireless communication network, that is, the cellular network 11a, is lower than the currently set deceleration value, the reception control unit 111 receives the data of the requested section 71. When the time is completed, the request by the communication protocol requesting the next section 60 ₂ is immediately transmitted.

As another embodiment of decelerating by requesting a data entity by dividing it into sections, as illustrated in FIG. 7B, the size S _{SEG_1} of the received section 711 at a time t711 when the requested section is received. Alternatively, the idle time T _idle2 ′ is calculated from the size S _{SEG_2} of the section 712 to be requested and the deceleration value specified in the current mode (721), and then waits for the idle time T _idle2 ′ and then the time point t712. Or, after that point, a request may be made for the next section 712 (or the ordered sections of other data entities). In this embodiment, since the time during which the requested interval is received is not taken into account in the deceleration calculation 721, the average load applied to the actual wireless communication network is lower than the set deceleration value. However, the set deceleration value is to keep the load applied to the wireless communication network below, and the error with the deceleration value as described above naturally meets this purpose.

In the above-described embodiments, when the data communication manager 110 sets a deceleration value in a wireless communication network currently used, the data communication manager 110 does not differentiate the process or the application that requested the data from the remote place through the local server 113, The reduced bandwidth is applied in proportion to the data rate used by the process or application. In other words, the speed at which the processes or applications read for each communication socket 22 ₁ , 22 ₂ ,... With the operating system 100a generated due to a remote data request through the data communication manager 110. So that the sum is limited to the specified deceleration, or that the request interval rqT _i in terms of the total N data entities requested by the processes or applications conforms to the specified deceleration, so that the request from the perspective of each data entity The interval is ΣrqT _i , so that the data received by each process or application is continuously made, but each speed occupies a random ratio in the range of the designated deceleration value. In other embodiments according to the present invention, when a deceleration value is set in the wireless communication network to be used, the process or applications for requesting remote data from the outside of the data communication manager 110 are discriminated, for example, at least in part. By blocking data reception, the load applied to the currently used communication network may be lower than or equal to the set deceleration value. Hereinafter, this embodiment will be described in more detail.

In the present embodiment, when the local server 113 transmits a request according to a communication protocol received through an internal communication socket to the data transmission / reception unit 112, the sender of the request according to the communication protocol, that is, the data communication manager. (110) It also forwards the IP address (including port number) of the external process or application. When the data transmission / reception unit 112 generates a communication socket as described above for the request according to the received communication protocol, the data transmission / reception unit 112 stores the identifier of the communication socket in association with the received IP address. In this manner, the data transmission / reception unit 112 creates and operates a data reception status table 91 having a structure as illustrated in FIG. 9 for managing by the sender for the request by the requested communication protocol. In one embodiment according to the invention, the data reception status table 91 is only registered for the wireless communication network to which the deceleration value is applied, for example, the communication socket created for use of the cellular network 11a. Since a plurality of communication sockets may be generated when one sender sends a request based on a plurality of communication protocols, a plurality of communication socket identifiers may be described corresponding to the same IP address as illustrated in FIG. 9 (92) ). Then, by measuring the speed of the data received through each communication socket listed in the data reception status table 91, as shown in Figure 9, the corresponding speed field 911 of the data reception status table 91 Will be written on One method of measuring the data reception speed is to repeatedly measure the amount of data received over a certain time (actually read through the corresponding communication socket) through the corresponding communication socket, and to receive the corresponding communication socket from the average of the measured values. The speed is determined. This value is constantly updated.

On the other hand, if the currently designated mode designates the deceleration value, and the communication network to which the deceleration value is to be applied is currently used, the reception control unit 111 periodically requests the data transmission / reception unit 112 for use status information for each process or application. . In response to the request, the data transmission / reception unit 112 returns the information to access the data reception status table 91 to the reception control unit 111, and the reception control unit 111 returns the returned access information. By using all the speeds of the use speed field 911 of the status table to determine whether the value is greater than the currently specified deceleration value. If the summed value is less than the currently designated deceleration value, it is checked whether or not the deceleration value is higher after the predetermined period. If the summed value is greater than or equal to the currently specified deceleration value, the reception control unit 111 determines which sender's data is to be blocked based on the status table 91. In one embodiment according to the invention, the data is blocked for the smallest number of senders so that the overall utilization rate is below the currently specified deceleration value. To this end, the reception control unit 111 adds sequentially from the lowest utilization speed as illustrated in FIG. 9 (93) and if the sum is exceeded the currently specified deceleration value (931), the excess caller It is determined that the caller 94 that is not involved in the utilization rate addition 93 to block the data. In the example of FIG. 9, it is shown that the sender to block data is determined when the currently designated deceleration value is assumed to be 500 kbps. The reception control unit 111 may identify the identifiers 941 of the communication sockets generated for the caller (IP address) 94 determined to block data or information that may be accessed by specifying the data transmission and reception unit 112. Request to close the communication socket. Upon receiving the request, the data transmission / reception unit 112 requests the communication socket to be closed while providing the corresponding communication socket identifier to the operating system 100a. In response to the request, the operating system 100a uses the corresponding communication socket. By removing and requesting the corresponding remote to terminate the session established for the communication socket, no further data transfer can be made. The determination of whether or not to block such data is made every cycle of the usage status information request as described above.

In another embodiment according to the present invention, the deceleration value is specified in the current mode by blocking the data as described above without mediating the remote data required by other processes or applications running on the wireless communication terminal 100. If so, the load on the wireless communication network, for example, the cellular network 11a, can be made to be below the deceleration value. FIG. 10 illustrates a configuration of the data communication manager 110 ′ according to the present embodiment, and is implemented or installed in the wireless communication terminal 100 in the same manner as the data communication manager 110 described above. It is executed by the main control unit 10 on the basis of 100a. The data communication manager 110 ′ illustrated in FIG. 10 includes a reception monitoring unit 114 and a data transmission / reception unit 115, and the data transmission / reception unit 115 requires a reception control unit 111 ′. It performs the function of exchanging information or information to be provided to the outside with the external server through the wireless communication network currently connected to the wireless communication terminal 100 based on the operating system (100a). In addition, the reception monitoring unit 114 repeatedly checks the communication status for each process or application that is performing data communication in the wireless communication terminal 110, calculates a data use rate of each process or application, and calculates the data usage rate of the process. 111 '). When the current deceleration value is to be applied, the reception controller 111 ′ determines a process or an application to stop execution by using the transmitted information. Hereinafter, the above operation of the data communication manager 110 ′ will be described in detail.

The reception monitoring unit 114 requests the operating system 100a repeatedly at predetermined intervals or at predetermined time intervals, and the structure as illustrated in FIG. 11 for the wireless communication network to which the deceleration value is to be applied. Obtain and request data communication details of 1110 _k , k = 1, 2,. When data communication details of all the communication networks available to the wireless communication terminal 100 are provided from the operating system 100a, only the information on the wireless communication network to which the deceleration value is to be applied is extracted as illustrated in FIG. 11. Done. The data communication history (1110 _k), there is the identifier of the transmission data amount and the data transmitted and received up to the time of request and or object was in, for example, process ID are recorded, respectively. When the reception monitoring unit 114 acquires or configures the data communication history 1110 ₂ (t ₂ ), for each process described in the communication history 1110 ₂ , the data communication history obtained earlier (t ₁ ) is obtained. Comparing with the corresponding information described in 1110 ₁ , the amount of change in the amount of data received is calculated, and when each amount of change is calculated, the reception monitoring unit 114 calculates the time interval between the acquisition points for the calculated amount of change. Each data rate is calculated by dividing by (t ₂ -t ₁ ), that is, by period (S1110). When the speed of the received data of each process is calculated, the reception monitoring unit 114 creates or uses the utilization speed status information 1120 having a structure as illustrated in FIG. Done.

When the information is updated, if there is a process identifier in the utilization speed status information 1120 previously created, which is not listed in the currently acquired data communication history 1110 ₂ , the entry 1121 is displayed in the status information 1120. Deletes and if the same process identifier is present, the calculated data rate is reflected to the average data rate described in the entry (S1110). The entry is newly registered (1122). When newly listing, the number of times the data rate was detected for the process, that is, 1, is also described (1122a). When the calculated data rate is reflected for each process listed in the status information 1120, the number of times described for the entry is first read (1131) (adding 1 to this read value to update the number of times described). to 1132), based substrate is the average velocity (ArDS _jO) to that of the value obtained by multiplying the number of times that has been read out is the calculated data rate summing speed (rDS _j) the read number of times than the process of dividing one number greater embellish that (1133). The average data rate field is updated with the value ArDS _jN obtained by this process 1133 (1134). In one embodiment according to the present invention, the reception monitoring unit 114 does not update the described number of times if the number of times of reading of any entry of the status information 1120 is a predetermined limit value, and the number of readings is not updated. The processes 1133 and 1134 are performed by considering the number of times that the number subtracted from the number is read.

Meanwhile, as in the above-described embodiment, the reception controller 111 ′ receives and sets the mode profile 110a and the mode policy 110b through the data transceiver 115 and set the mode profile 110a. And a current mode is designated according to the mode policy 110b, wherein the designated mode defines a deceleration value, and a communication network currently used by the wireless communication terminal 100 is a communication network to which the deceleration value is applied, for example, the cellular network. If the network 11a, the reception monitoring unit 114 periodically requests the use speed status information. In response to this periodic request, the reception monitoring unit 114 generates the utilization speed status information 1120 or information for accessing the status information, which are prepared as described above and periodically update and record the data reception speed. The receiving control unit 111 'uses the returned information to determine an entity to stop execution so that the total data use speed ΣArDS _jN is equal to or lower than the currently specified deceleration value. Of course, if the total data use speed is less than the currently specified deceleration value, the entity to be stopped is not determined. When it is necessary to determine the object to be stopped, the method 93 described with reference to FIG. 9 may be applied as one of the determining methods. In other words, the objects to be stopped are selected such that the sum of the data rates to be used is the minimum number of objects except those whose values are less than or equal to the deceleration value. The reception control unit 111 'requests that the execution of the selected object be interrupted while providing the entity ID, for example, the process ID, described in the utilization speed status information 1120 to the operating system 100a. In response to this request, the operating system 100a forcibly stops the execution of the entity specified by the identifier and recovers the resources occupied by the entity. Such determination of whether to stop the execution entity is made every cycle of the request for utilization speed information as mentioned above.

In another embodiment according to the present invention, instead of stopping the execution object so that the speed of use of the wireless communication network is less than or equal to the deceleration value, the execution state of the object may be maintained, but only data transmission and reception of the object may be blocked. For example, when the operating system 100a has a function of blocking transmission and reception of the data for a specific process, the reception control unit 111 'is an identifier of the entity instead of a request for stopping the execution of the entity. It may be requested to force the transmission and reception of the data to the operating system 100a while providing.

In one embodiment according to the present invention, the reception control unit 111 ′ may inquire the user of the wireless communication terminal 100 whether to stop the execution before stopping the execution of the object selected to be stopped. To this end, if necessary, the reception control unit 111 ′ obtains a package name for the object to be stopped, and together with the query window displayed on the display panel 5 to inquire whether or not to stop. You can also provide The package name may be checked from a list of object identifiers and package names obtained by requesting the operating system 100a for information on processes or applications currently running. The query window is displayed on the screen using an appropriate API provided by the operating system 100a, and the reception control unit 111 'returns the selected information through the query window to return information of the operating system 100a. After confirmation from the user, the object selected to be stopped is requested to stop its execution while providing the object identifier to the operating system 100a as described above.

In another embodiment according to the present invention, an object selected to be stopped may be confirmed through a query window, and the user may directly perform the execution without stopping the object. At this time, the reception control unit 111 'provides the information of the execution object selected to be stopped only through the notification window on the display panel 5, and the user, for the execution object presented in the notification window, It may be selectively forcibly terminated through a control application basically provided to the communication terminal 100. The reception control unit 111 ′ also includes a data rate (for example, an average speed ArDS _jN described in the utilization speed status information 1120 of FIG. 11) used by the execution object for the object presented in the notification window. Can also be displayed. In addition, when the reception control unit 111 'needs to apply a deceleration value to a wireless communication network currently being used, the total data utilization rate (ΣArDS _jN confirmed from the utilization speed status information 1120 of FIG. 11) is the deceleration value. If not, select the object to be stopped, and display a notification window that lists all of the processes or applications that are currently using the data service (for example, execution objects listed in the utilization speed status information 1120). It can also be output on the panel 5 together with the respective current speed of use. At this time, the information on the currently applied deceleration value may also be displayed. As such, when the user leaves the interruption through the notification window, the reception control unit 111 ′ monitors the execution of each object. If a predetermined time, for example, 2 minutes elapses after outputting a notification window, the current status of the process being executed is requested by the operating system 100a at that time, and the execution objects listed through the notification window are obtained from the obtained process status. If it is missing, the object is considered suspended by the user.

As in the above-described embodiments, when the reception control unit 111 'forcibly stops executing a specific object or forcibly blocks data transmission or reception, or when an artificial interruption by a user is confirmed, The information that can identify the object (for example, the package name checked from the operating system 100a for the object) and the degree of load reduction due to the suspension of execution of the object, for example, use of FIG. In the speed status information 1120, load reduction information including information such as the average speed ArDS _jN described for the object interrupted or interrupted in communication is configured, and the data transmission / reception unit 115 performs the above-described information. It may be provided to the load control server 13 that provides mode-related information, or to a traffic monitoring server that monitors the traffic state of the cellular network 11a as a whole. Of course, at this time, the reception control unit 111 ′ obtains information uniquely identifying the wireless communication terminal 100, for example, a subscriber's telephone number, from the operating system 100a and included in the load reduction information. Will be provided.

As in the above embodiments, if the deceleration value is specified in the currently selected mode, the load applied by each wireless communication terminal to the mobile phone communication network, for example, the cellular network 11a, is at a speed below the deceleration value. Will decrease. Accordingly, the reception control section 111 of each wireless communication terminal is properly specified by externally defining the mode profile 110a and the mode policy 110b illustrated in FIGS. 3A and 3B to which the reception control section 111 or 111 'is referred to. Or 111 '), it is possible to prevent a service failure due to traffic temporarily applied to the cellular network 11a. For example, as shown in FIG. 3B, an arbitrary service area (eg, a cell which is an area managed by one base station of a cellular network, a service zone of an access point of a Wi-Fi network, and a cell) For a specific area, or femto cell managed by a small base station, during a time when statistically heavy traffic is concentrated (or, as shown in FIG. 3C, the service area (X, Y) that has a heavy traffic load on average) For mode C, which is to be greatly decelerated, and during the time when a considerable amount of traffic is maintained (or as for the service area (F, G, H) with a heavy traffic load on average, as shown in FIG. 3C), Specifies mode B that allows deceleration to occur, and does not decelerate during periods of traffic within an acceptable range (or for the remaining service areas, as shown in FIG. 3C). A mode policy specifying A may be determined and provided to the reception control unit 111 or 111 '. Of course, the mode designation according to the time zone and / or day of the week defined by the mode policy 110b may be naturally specified because the time zone where the traffic is concentrated or its aspect is different according to the service area of the cellular network 11a. The same is true for the mode profile 110a in which an example is shown in FIG. 3A. Since a difference occurs in the concentration of traffic and the like for each service area, even in the case of a deceleration value for each mode, it may have a different value between the mode profiles allocated to each service area. For example, the deceleration of mode B or C of a mode profile to be applied to a service area with high concentration of traffic is smaller than the deceleration of mode B or C of a mode profile to be applied to a service area with less concentration. (I.e., a value that makes the deceleration greater is specified.). In addition, the mode profiles may be assigned different numbers of modes according to the traffic concentration of the service area to which the profile is allocated or the degree of change thereof.

As described above, in order to load control the cellular network 11a according to the current service area of the wireless communication terminal 100, the reception control unit 111 of the data communication manager 110 or 110 ′. Or 111 ') may include identification information (e.g., cell identifier or access point identifier (e.g., MAC address of the AP) that informs the changed service area when the service area using the current data service is changed; The femtocell identifier, or the latitude and longitude coordinate information, etc.) is provided to the load control server 13 through the data transmission / reception unit 112 or 115, and requests and receives a profile and a policy related to mode setting to determine a mode based thereon. The requirements specified in the mode will be applied. In one embodiment according to the present invention, it is also possible to intermittently check the latitude and longitude coordinate information where it is located and provide it to the load control server (13). The cell identifier or the access point identifier may obtain the information by requesting the operating system 100a, and the reception control unit 111 or 111 'may change the service area when the operating system 100a changes the service area. You can also know the service area change by detecting the events that occur. The latitude and longitude coordinate information may be obtained by requesting the operating system 100a when the GPS module is provided in the wireless communication terminal 100. At this time, the activation of the corresponding GPS module may be additionally requested to the operating system 100a. In addition, the reception control unit 111 or 111 'has an access address, for example, a URL, that is set in advance so as to request information related to mode setting from the load control server 13, or in a form suitable for a user. It may be set as environment information by being input through the provided UI screen.

In another embodiment according to the present invention, mode-related information allocated to the service area is automatically transmitted from the load control server 13 without the request of the reception control unit 111 or 111 '. May be provided at '). In the present embodiment, when the base station (or the small base station) of the cellular network 11a recognizes the entry into the corresponding service area of the wireless communication terminal 100 (when the area is within the service area, The location of the terminal can be recognized by estimating the location of the terminal using the reception sensitivity of each arriving terminal signal, or the terminal can be recognized by registering the terminal with the small base station of the corresponding area. It provides the information of the terminal to the exchanger that manages the terminal and registers the terminal in the subscriber information processing device (HLR: Home Location Register). At this time, the access IP address for providing the data service is also registered. The terminal is assigned an IP address from the cellular network 11a) or a new IP address is assigned to the terminal (or Through-type base stations) and provides the wireless communication terminal 100. The subscriber information processing device transmits the IP address of the terminal registered to the subscriber and the identification information of the corresponding service area to the load control server 13 through a dedicated communication network established separately. Then, the load control server 13 reads the mode-related information assigned to the service area in the same manner as the case where the mode-related information is requested in the above-described embodiment, and receives the notification from the subscriber information processing apparatus. Opens a connection with the IP address as the destination and sends it through the connection. In order to transmit the mode-related information to the terminal of the corresponding IP address to the data communication manager 110 or 110 ', preferably, a fixed port number is assigned to the data communication manager 110 or 110. ') Is used, and this port number is already reserved with the load control server (13). In this manner, upon entering an arbitrary service area, the data communication manager 110 or 110 ′ receives mode-related information allocated to the service area without a request thereof, and the received mode-related information is received by the reception control unit ( 111 or 111 '), it is used to confirm the mode and usage requirements to be applied currently.

In addition to changing the service area, the reception control unit 111 or 111 ′ obtains information that enables the user to know the service area at the time when the screen lock state of the wireless communication terminal 100 is released, and the information. Is provided to the load control server 13 while receiving the mode profile and mode policy appropriate to the region through the data transmission and reception unit 112 or 115. In addition, the reception control unit 111 or 111 ′, when the communication network used to use the data service is switched (for example, between 3G network and LTE network, or between 3G network and Wi-Fi network). In addition, it is also possible to obtain information that allows the service area to be known about the switched communication network, and to receive and apply a mode profile and a mode policy appropriately defined for the corresponding area based on the information. The reception control unit 111 or 111 ′ recognizes the switching of the communication network by detecting the event generated by the operating system 100a.

On the other hand, the load control server 13 partitions the entire area or a part of the serviceable area of the cellular network 11a by area, and the database 13a for area partition information for controlling traffic conditions. ) Is provided inside or externally connected via a dedicated line, etc., and this database 13a is allocated with mode-related information for each service area according to the area partition information, as illustrated in FIG. 8. And stored. More specifically, for the cells of the cellular network 11a, identification information (eg, base station identifier) 801 of the cell, location information (eg, coordinate information on an area boundary, etc.) of the corresponding cell, or corresponding Location information 802 for specific zones in a cell, identification information 803 of each access point of the Wi-Fi network 11b having a service zone in the cell, and mode profile and mode policy set for the cell; 804 is stored in association. In addition, mode-related information may be partially allocated to one cell. For example, as illustrated in FIG. 8, a plurality of different mode related information 811 may be stored in association with one cell 810. In the example of FIG. 8, the cell 810 is divided into three areas, and mode related information is allocated to each cell. In the case of the lower two entries 810a, the service of the Wi-Fi network 11b is provided. Mode-related information is specified differently according to zones (i.e., by access point or access point group), and in the case of the upper one entry 810b, separately for a specific area without an access point of the Wi-Fi network 11b. Mode-related information is specified.

Each mode profile and mode policy are appropriately prepared as illustrated in FIGS. 3A and 3B in consideration of the average traffic volume of each cell day and / or time zone, traffic concentration, and change degree. In addition, as in the above-described embodiment, the mode policy may be created as illustrated in FIG. 3C by reflecting the traffic concentration characteristic of each region, and may be created together with the application priority information by appropriately combining FIGS. 3B and 3C. It may be. The database 13a is constructed to use cell identifiers, location information, and AP identification information as indexes.

Therefore, the load control server 13 is connected to the cellular network 11a or the Wi-Fi network 11b via a dedicated line and the like through its communication means for exchanging data. 110 or 110 ′, when receiving information for identifying a service area of a wireless communication network currently used, for example, a cell (or femtocell) identifier or an AP identifier or receiving coordinate information of a current location, By searching the database 13a on the basis of the information related to the entry (entry) having an identifier that matches the corresponding identification information or the mode-related information (mode profile and mode policy) of the entry having the location information to which the corresponding coordinate information belongs, It is provided as a response to the data communication manager 110 or 110 'through the provided communication means. Of course, this answered mode profile and mode policy are received by the receiving control 111 or 111 ', as described above, and used to determine the current mode and apply the requirements specified in that mode.

In the above embodiments, only the deceleration value or the deceleration value of the use speed for the wireless communication network is specified and used in the mode profile. However, in other embodiments according to the present invention, in addition to the above-mentioned deceleration value for suppressing the utilization speed of the cellular network 11a in the mode profile, other wireless communication networks, for example, the Wi-Fi network 11b. The usage threshold value, which is a connection allowance reference value for inducing the use of), may be further specified as a use requirement.

FIG. 12A is an example of a mode profile created according to this, and is stored in the database 13a as in the above-described embodiments, and is stored in the database 13a by the load control server 13. 110 'to the reception control section 111 or 111'. The example of FIG. 12A can be used when the signal characteristics indicating the quality of the Wi-Fi network 11b, for example, when the signal strength is quite good, in a state where the cellular network 11a can be freely used without limitation. In addition, in the state where the usage limit for the cellular network (11a) is required to show that the usage threshold is lowered so that the Wi-Fi network (11b) can be used even at a lower signal strength, the presented numerical value is Only one example may be applied in a manner different from the one illustrated, in a manner consistent with the above rules. Of course, as in the above-described embodiments, a different usage threshold may be specified for each mode for each cell of the cellular network 11a. In addition, in one embodiment according to the present invention, even if the same cell in the cellular network (11a), different usage thresholds can be applied according to the service zone of the Wi-Fi network (11b), the database 13a ), A plurality of mode profiles and mode policies may be stored in the case where the access point is different even though belonging to the same cell. In this case, a mode profile and mode policy designated as a representative are provided by the load control server 13 when a cell identifier is received, and when a connection point identifier or coordinate position information is received, a plurality of profiles and policies for the corresponding cell are received. Among them, a mode profile and a policy corresponding to the connection point identifier or the coordinate position information are specified and provided.

As illustrated in FIG. 12A, when setting a usage threshold for the Wi-Fi network 11b of each mode in a mode profile, the average provided at an appropriate load state in the service area of the cellular network 11a is provided. It may be determined in consideration of the data service speed. For example, if the service speed of the cellular network 11a in the service area related to the mode profile to be created is 1.2 Mbps on average, the Wi-Fi network 11b is at least equal to (or at a predetermined ratio) under an appropriate load state. For example, a value of signal strength (-60 dBm in the example of FIG. 12A) 121 that shows, on average, the characteristic that a service rate is provided, may be specified for mode A. This is to reduce the likelihood that the service speed will be lowered, even if the user switches to the Wi-Fi network 11b while using the cellular network 11a without restriction in the region. In the case of mode B, since the utilization speed is limited to the deceleration value specified in the cellular network 11a, the unused data rate (700 kbps (= 1.2 Mbps-500 kbps) based on the illustrated value) is therefore reduced. Or a value of signal strength (-70 dBm in the example of FIG. 12A) 122 that shows, on average, a characteristic that can at least provide the average provision rate of the cellular network 11a (1.2 Mbps, illustrated above). It can be specified as a usage threshold. In the former case, if the wireless communication terminal 100 can use a plurality of wireless communication networks at the same time, at least as long as the wireless communication terminal 100 cannot use the communication resources, that is, the transmission bandwidth of the cellular network 11a by deceleration, at least the Wi-Fi network By replenishing the transmission bandwidth in (11b), if data reception is divided into multiple communication networks and received in parallel, the data rate used is not decelerated in spite of the deceleration in the cellular network 11a. In order to ensure that at least the average speed provided by the cellular network 11a is guaranteed when the converted speed is switched to the Wi-Fi network 11b because it is not suitable for current service use, for example, content play. It is set. In a mode in which the deceleration of the cellular network 11a is maximized (mode C in the example of FIG. 12A), it can be used without considering the quality of service for the communication resource to be replaced, that is, the Wi-Fi network 11b. Threshold is not specified. The above description is merely one example of determining the usage threshold of each mode for the Wi-Fi network 11b, and the cellular network 11a without consideration of the service speed provided by the cellular network 11a. For each mode as a value of signal strength that makes the connection more easily attempted within the range that the Wi-Fi network 11b provides an appropriate service rate as the deceleration becomes more severe, that is, the stronger its use is suppressed. May also be specified for.

As in the embodiment described with reference to FIG. 12A, when a usage threshold for another wireless communication network of a wireless communication network that is decelerated according to a mode is specified in a mode profile, the reception of the data communication manager 110 or 110 ′ is performed. The control unit 111 or 111 'periodically checks whether another communication network, for example, the Wi-Fi network 11b, is available when the cellular network 11a, which is currently a public telephone communication network, is a use communication network. In one embodiment according to the present invention, only when the use of the Wi-Fi network 11b is currently activated in the configuration of the wireless communication terminal 100, it may be periodically checked whether the communication network is available. The reception control unit 111 or 111 'may determine whether the Wi-Fi network 11b is available by requesting and receiving information on the state of the Wi-Fi network from the operating system 100a. The operating system 100a controls the Wi-Fi modem 2a to physically search the Wi-Fi signal band for a Wi-Fi network state information request, and then, the Wi-Fi modem 2a ) Reads the identification information of each access point and the value of RSSI (Received Signal Strength Indicator) provided when the valid signal is detected in the corresponding signal band (r11 in FIG. 1B). If there is no access point in the returned information, the reception control unit 111 or 111 'determines that the current Wi-Fi network is not available.

If the signal strength of the connection point in the current region of the Wi-Fi network 11b periodically checked in this way is higher than the usage threshold determined in the currently designated mode, the reception control unit 111 or 111 'may determine the Wi-Fi. The operating system 100a is requested to switch the connection to the network 11b. If there are a plurality of connection points showing the signal strength above the usage threshold, the connection point with the highest signal strength is designated and the connection request is made to the operating system 100a.

In another embodiment according to the present invention, the usage threshold set for the Wi-Fi network 11b may be designated as a quality score instead of a signal strength. 12B is an example of a mode profile created according to this embodiment. The usage threshold 125 based on the illustrated quality score is a score determined by variables such as characteristics indicating service quality, for example, service speed (SSpd), connection success rate (AccHR), and signal strength (SStr). The score QPt is a value obtained by multiplying and adding an appropriate weight to the score given to the current value of each variable, as in the following equation (1), with 0 to 100 points assigned to the variable range of each variable. to be.

QPt = α · SSpd + β · AccHR + γ · SStr (0 ≦ α, β, γ ≦ 1, α + β + γ = 1) Equation (1)

The reception control unit 111 or 111 ′ has previously stored and managed its own connection point in order to know a current quality score for any connection point retrieved from the Wi-Fi network 11b. Each score for the variable based on the number of connection attempts until the connection request is successfully assigned and the IP address assignment is successful (the higher the number, the lower the number given), and the average service speed when the connection point is used. Is calculated from each of the scores thus calculated and the signal strengths of the arbitrary connection points currently identified (a table or equation for calculating the score for each variable value is previously described in the reception control unit 111 or 111 '). The final quality score is obtained by substituting the score into Equation (1) above, and the current quality score obtained is compared to the current mode of the currently set mode profile. It is compared with the threshold value used.

In another embodiment according to the present invention, the quality control score is not directly calculated by the mobile communication terminal 100, but the access control server (not shown) whose access information is preset in the reception control unit 111 or 111 '. In addition, while providing identification information of each access point of the Wi-Fi network 11b retrieved from the current location, it is also possible to receive and use the current quality score for the access point. To this end, the access control server, in real time, from the operating system or the application (including the data communication manager 110 or 110 ') of the wireless communication terminal using the Wi-Fi network (11b), when the signal strength, connection success The number of attempts up to and the data rate to be used are reported, and the current quality score for the corresponding connection point is calculated and stored from each value for each report. Of course, since different terminals report different values for a single access point, the access control server calculates a final quality score from an average of the reported values, or the quality score calculated from the reported values of each terminal. The final quality score is calculated by averaging them, and the final quality score of the corresponding access point is provided when the quality score is requested from the wireless communication terminal.

In one embodiment according to the present invention, in addition to the usage threshold for the Wi-Fi network 11b in the mode profile, a termination threshold for terminating the use may also be included as a usage requirement. The termination threshold is a reference value for releasing the use of the corresponding communication network and switching to the cellular network 11a to which the deceleration value may be applied. The termination threshold may be set to have a lower reference value than the use threshold specified in the same mode. This is to reduce the possibility that the use of the Wi-Fi network (11b) may be suspended due to instantaneous volatility despite the average stability. In the present embodiment, the reception control unit 111 or 111 ', the characteristic value confirmed for the connection point of the Wi-Fi network 11b, for example, signal strength or the above-described quality score is more than the use threshold specified in the current mode. In this case, the connection to the corresponding connection point is made. If the signal strength or the quality score of the connection point is lower than the termination threshold while using the Wi-Fi network 11b, the connection to the cellular network 11a is performed. The operating system 100a is requested to be switched. In this switching, the reception control unit 111 of the data communication manager 110 having the structure as illustrated in FIG. 2 is transferred from the cellular network 11a described below to the Wi-Fi network 11b. The operation of data loss without loss is performed as is.

Meanwhile, in the embodiment in which the data communication manager according to the present invention has a configuration as illustrated in FIG. 2, the data communication manager 112 is configured to communicate with the communication protocol through the data transmission / reception unit 112 while the cellular network 11a is currently in use. If the response to the request is being decelerated as described above or being received without restriction, if the signal strength or quality score of the access point of the Wi-Fi network 11b that is currently confirmed is equal to or higher than the usage threshold specified in the corresponding mode. As described above, the reception control unit 111 requests the operating system 100a to switch the use communication network. In response to the request, when the operating system 100a notifies the reception control unit 111 that the connection has been successfully switched from the corresponding access point of the Wi-Fi network 11b, the reception control unit 111 receives the access control unit 111. ) Requests the data transmission / reception unit 112 for a status of use of the wireless communication network, that is, the cellular network 11a, before the connection is switched. When this request is made, the data transmitting / receiving unit 112, as in the example of the schematic data reception state of FIG. 13, has a communication socket 131 that has been created to use the cellular network 11a. If the data amount 1311 being monitored as described above with respect to the communication socket 131 is not zero, the amount of data received up to that time through the communication socket 131, i.e., the monitored data amount 1311 and The request 1312 according to the communication protocol transmitted to receive the data is returned to the reception control unit 111 together with information of the last position where the data received from the communication socket 131 is stored. Then, the reception control unit 111 modifies 1322a the request 1312 by the communication protocol so that the data after the received data amount is received, and then requests the request 1322 by the modified communication protocol. While transmitting to the data transmitting / receiving unit 112, the next position of the last position that was returned by the user is designated as the data storage position. According to this request, a communication socket 132 to use the Wi-Fi network 11b is generated, and through the communication socket 132, the section of data requested by the request 1322 according to the modified communication protocol ( 1330 (data following the section 1310 that was received through the cellular network 11a) is received by the data transmission / reception unit 112, and the data is stored from the previously designated data storage location. That is, the data section 1330 subsequent to the data section 1310 previously received through the cellular network 11a is received through the switched Wi-Fi network 11b and stored in order. The data stored in this way is directly provided to the local server 113 or provided to the local server 113 under intermediation of the reception control unit 111.

In the above-described embodiments, the data communication manager 110 or 110 ′ selects one mode based on the mode profile and the mode policy currently set to the wireless communication network according to the requirements specified in the selected mode. You choose to use it or use it by other objects (process or application, etc.). In another embodiment according to the present invention, the data communication manager 110 or 110 ′ may directly use the wireless communication network or allow another entity to use the data communication manager 110 or 110 ′. In one embodiment according to the invention, the instructions from the outside at this time are preferably via the cellular network 11a. And the instruction is received from the load control server 13 or an operation control server built separately from this. In the following description, it is assumed that the load control server 13 transmits the instruction for convenience of explanation. And this instruction is forcing to designate one mode in the mode profile previously set in the data communication manager 110 or 110 'in each wireless communication terminal or irrespective of the mode specified in the mode profile. It may be to force to set any deceleration value for the cellular network (11a). When combined with the embodiment described with reference to FIG. 12B, the indication may also include a usage threshold or a termination threshold of the Wi-Fi network 11b. In this embodiment, as illustrated in FIG. 14A or 14B, the reception control unit 111-1 or 111 ′-1 of the data communication manager 110-1 or 110 ′-1 controls the command detection unit 111a. It includes.

The command detection unit 111a uses a communication information API for the cellular network 11a provided by the operating system 100a to control signals transmitted and received via a radio signal of the cellular network 11a, for example. For example, the signal on the paging channel in the signal format as illustrated in FIG. 15 is periodically checked. A base station (or a small base station) connected to an exchange station constituting the cellular network 11a (hereinafter, the term “base station” is used to include a small base station unless technically the application thereof should be excluded.) 15 always exchanges a radio signal of a signal format as illustrated in FIG. 15 with a mobile station such as the radio communication terminal 100. Accordingly, the load control server 13 receives a report on the amount of traffic applied to the service area of each base station, determines whether the traffic amount is concentrated at an instant, and it is necessary to urgently regulate the use traffic, and determines that emergency regulation is necessary. For the service area, the emergency load control information for the base station is transmitted to the switching center of the base station through the dedicated communication network. The emergency load control information for mandatory regulation may be generated by the load control server 13 according to a regulation rule according to the traffic volume, or may separately manage traffic for the cellular network 11a. Can also be obtained from the server. Upon receiving the emergency load control information through the switching center, the target base station inserts the emergency load control information into an appropriate position in the radio signal format and transmits the radio signal. The emergency load control information in the format as illustrated in FIG. 15 is decoded by the cellular codec 1b of the mobile stations including the wireless communication terminal 100 located in the cell of the base station, so that the operating system 100a can be decoded. Is provided. Instead of the periodic confirmation, the command detection unit 111a requests a registration signal to the operating system 100a to generate an event to itself when specific emergency load control information is received. It may be confirmed that the communication terminal 100 has received.

The emergency load control information intended to be detected by the command detection unit 111a is an identifier 1501 assigned to a message type such as paging, command, etc. previously defined and used in a radio signal protocol between the cellular network 11a and the terminal. ), Which is different from the " offloading " identifier 1511, is a signal that has been transposed, and the message 1510, in which the load reduction identifier 1511 is transposed, includes the mandatory regulatory information as described above, That is, information 1512 of the forced mode or the forced requirement (deceleration value, etc.) is loaded. Accordingly, the command detection unit 111a may load the load reduction message 1510 in the wireless signal of the cellular network 11a received in the region where the wireless communication terminal 100 is located. The reception control unit 111-1 or 111 ′-1 checks the information 1512 of the forced mode or the mandatory requirement contained in the received message through the command detection unit 111a. If the confirmed information is the forced mode, the reception control unit 111-1 or 111'-1 specifies the forced mode in the mode profile regardless of the currently set mode policy, and then the requirements specified in the mode (this requirement is decelerated). The value may be 0.) A wireless network is used. If the received information is a mandatory requirement, regardless of the mode policy and mode profile currently set, the wireless communication network is used as described above according to the requirement.

In one embodiment according to the present invention, the load reduction message 1510 may include information on the length of time or time period during which a forced mode or a forced requirement persists. If such information is included in the load reduction message 1510 detected by the command detection unit 111a, the reception control unit 111-1 or 111'-1 is applied for the time length after the application of the forced mode or the forced requirement. After elapsed or after that point, one mode is determined according to the currently set mode policy, and then the wireless communication network is used according to the requirements specified in the currently set mode profile for the mode.

In one embodiment according to the present invention, the mandatory requirement included in the load reduction message 1510 may include a list including an application to block its execution. The app list includes information identifying the app, for example, a package name. When the compulsory requirement detected by the command detection unit 111a includes an app list including at least one executable application, the reception control unit 111'-1 of the data communication manager 110 'is shown in FIG. The usage speed status information 1120 having the structure as illustrated is periodically checked, and if the checked status information includes the app on the app list, the execution is stopped in the same manner as in the description of the above-described embodiment. Let's go. In order to specify an application in this process, as described above, the package name of execution applications obtained from the operating system 100a may be used. In addition, if a deceleration value is also specified in addition to the list of applications in the detected mandatory requirement, the reception control unit 111'-1 excludes the object corresponding to the suspended application, and uses as illustrated in FIG. The speed status information 1120 is used to select an additional object to stop execution in order to be below the designated deceleration value.

In one embodiment according to the present invention, the load control server 13 instructs the release of the load reduction if it is determined that the release is necessary in view of the amount of traffic monitored for the service area that sent the forced mode or the forced requirement. The emergency load control information is transmitted to the corresponding base station, and the base station constructs a message 1520 including an identifier 1521 instructing to release the load reduction as illustrated in FIG. 15 based on the control information. In the radio signal format to be exchanged is inserted in the appropriate position to send. As described above, when the transmitted signal is in the service area, the reception control unit 111-1 or 111'-1 detects the release command through the command detection unit 111a, and the release command is detected. If so, the reception control unit 111-1 or 111'-1 makes an original normal mode decision. That is, after determining one mode according to the currently set mode policy, the wireless communication network is used according to the requirements specified in the currently set mode profile for the mode.

In the state in which the forced mode or requirement is set, the forced mode or requirement is canceled even when there is a service area change in accordance with the movement of the mobile communication terminal 100. FIG. 16 is a diagram to help understand this process, in which a service area is a service area of the cellular network 11a. However, a change to another service area, for example, a change in an access point of the Wi-Fi network 11b, or an entry into an access point (in this case, a cell from a cellular network to a service zone of a Wi-Fi network) In the case of entering or leaving a specific area within a cell of the cellular network 11a, the principles and concepts described with reference to FIG. 16 may be applied. As illustrated in FIG. 16, the reception control unit 111-1 or 111 ′-1 in the mobile communication terminal 100 receives the forced mode or requirement in the first service area 1611 so that the forced control mode or requirement is received. In the state of setting, when entering the other service area 1612 by the movement 1602 according to the user or other moving means, as described above, the reception control unit (111-1 or 111'-1) Recognizes the cell change through confirmation to the operating system 100a or by notification from the operating system 100a, and thus the current mode profile for the service area from the load control server 13. After requesting and receiving the over-mode policy, the mobile terminal releases the forced mode or the mandatory requirement that the user has used (1603). The mode to be used for the service area is determined according to the mode profile and the mode policy received in the service area.

On the other hand, the load control server 13, for the service area to which the mandatory mode or requirement is assigned as in the above-described embodiment to urgently regulate the use of the cellular network 11a, the mode for the service area. In order to assign a mandatory mode or a requirement even in response to a request for related information, as shown in FIG. 8, the mandatory regulatory information, that is, a mandatory mode or a mandatory requirement is stored in the database 13a in association with the entry 820. It is done. Of course, as described above, when the emergency regulation needs to be released for the service area, the stored forced mode or requirement 820 or the like is deleted or marked as inactive. When there is a request (a request by the cell identifier, access point identifier, terminal longitude coordinate information, etc.) of the entry (831,832) in which the forced mode or requirement is stored, the load control server 13 stores the associated information in addition to the mode related information. Compulsory regulatory information is also obtained from the database 13a and provided. This means that after a forced mode or a mandatory requirement is applied to wireless communication terminals located in the service area, when a new wireless communication terminal enters the service area, the mobile terminal is also subject to the forced mode or mandatory requirement. In order to use the wireless communication network accordingly. Also in this case, as in the above-described embodiment, a time length or time point during which the forced mode or the forced requirement persists may be provided together. Of course, in the case of providing a sustained time length, the calculated duration is provided by subtracting the elapsed time starting from the time when the force mode or the force requirement is first applied.

Therefore, when the reception control unit 111-1 or 111'-1 in any one of the above-described embodiments is received with a compulsory mode or a compulsory requirement in response to a request for mode-related information, the reception control unit 111-1 or 111'-1 first receives a compulsory mode or a compulsory condition. Use the wireless network to apply the requirements. When information on a duration or time point is received according to an embodiment of the present invention, when the duration or time point elapses, one mode is determined according to the previously received mode profile and mode policy. The wireless communication network is used according to the determined mode.

In the above-described embodiments, the load control server 13 has provided the wireless communication terminal with a mode profile in which a plurality of modes in which at least different usage requirements are specified are described. In another embodiment according to the present invention, the load control server 13 may provide the usage information to the wireless communication terminal specifying the single use requirement instead of the mode profile. The usage rule information may include mode information 1702 specifying the information 1701 in addition to the information 1701 on the usage requirement, as illustrated in FIG. 17A. Of course, as in the above-described embodiments, in the usage rule information 1700, only the deceleration value (or information on whether the deceleration) for the cellular network 11a is designated as the information 1701 for the use requirement. Also, in addition to the usage threshold 1703 for the access point of the Wi-Fi network 11b illustrated, the termination threshold may be additionally specified in the information 1701 on the usage requirement.

In the embodiment according to the present invention in which the usage rule information is provided to the wireless communication terminal, the load control server 13 includes a plurality of usage rules for which information on usage requirements, as illustrated in FIG. 17B, is differently designated. The regulation table 1710 including information is prepared or received from another server outside and stored. As illustrated in FIG. 17B, the regulation table 1710 may be prepared in a form in which respective usage regulation information is designated in correspondence with the information representing the traffic state in an arbitrary service area. Alternatively, it may be written only with the respective usage rule information and the information identifying the information. In this case, after the external server grasps the traffic state of the corresponding service area to determine specific usage rule information, the load control server 13 includes information for identifying the determined information together with the identifier of the service area. To be provided.

The load control server 13 selects and assigns usage rule information corresponding to the current traffic situation of the area from the regulation table 1710 to each service area according to the area partition information of the database 13a. (1711). Of course, this allocated usage rule information is then provided to the corresponding terminal in response to a request from the wireless communication terminal entering the corresponding service area or automatically entering the terminal as in the above-described embodiment. do. In addition, the load control server 13 continuously checks whether the traffic state is appropriate to the pre-allocated usage rule information for each service area, and if it is determined that the new usage rule information should be applied to the changed traffic state, The service area of the database 13a is updated with the new use rule information, while the wireless communication terminal in the service area is provided automatically or upon request from the terminal so as to receive the new use rule information. (1712). Instead of providing the individual usage rule information for the wireless communication terminals in the service area, as described with reference to FIG. 15, the usage rule information is broadcast to the wireless communication terminals in the area through a base station that manages the service area. It can also be applied collectively by sending the information to the paging channel. In addition, in the present embodiment, after the usage rule information corresponding to the traffic state of the area is allocated to a certain service area, the usage condition specified by the usage rule information enters into or enters the service area. Since it can be directly applied to the terminals, the mandatory regulatory information in the above-described embodiments can be designated and used as one of the usage rule information.

The various embodiments described so far may be selectively combined and implemented in various ways unless incompatible with each other.

In addition, the principle and concept of the present invention are presented by presenting the cellular network 11a as an example of a mobile phone communication network using a data service and the Wi-Fi network 11b as an example of a data service network.
